Hi,
yes, simply inverse the logic.
first action: compare with -90 and only fire an event "OUT OF RANGE" if smaller than -90
second action: compare with 90 and only fire "OUT OF RANGE" if greater than 90
now, if you are still in the state, it means your float is within -90 and 90, and use a send event action "WITHIN RANGE"
this kind of logic implementation is very important to understand, it's very powerful, it's often use in math to prove a theorem. If you can't prove it's possible, you can prove also that's it's impossible not to be
almost philosophical !
if you can't prove it's between -90 and 90, prove that it's smaller than -90 or greater than 90 which then must be between -90 and 90.
Bye,
Jean
